Definitions

• the present invention relates to means and method for feeding interlocking solid material to process apparatus and, more particularly, to means and method for feeding shredded tires to a tire liquefaction process apparatus.
• the present invention is a purge chamber which includes a chamber for holding interlocking solid material.
• An entrance port apparatus passes the interlocking solid material into the chamber where it is purged by a purging gas.
• An exit port apparatus passes the solid interlocking solid material from the chamber.
• moving apparatus which moved the interlocking solid material from the chamber through the exit port apparatus.
• yet another apparatus which prevent the binding of the interlocking solid material.
• Fig. 1 is a graphical representation of apparatus, constructed in accordance with the present invention, for the purge feeding of interlocking solid material to process apparatus.
• Fig. 2 is a isometric view of the chamber shown in Fig. 1.
• interlocking solid material refers to solid substances that, because of their shape and/or composition, have a strong tendency to knit together like entangled yarn. While the primary example of the present invention is related to discharging shredded tire pieces, other applications, such as woodchips, reinforce plastics and scrap may also be applicable.
• a chamber 3 with a top feed port 7 has support members 15 to give it greater strength.
• hanger bars 22 which are used to support a material drive system including a drive motor 27.
• a drive shaft 36, rotated by motor 27, is connected to a gear reducer 44.
• Gear reducer 44 also provides a 90°F translation of the driving force to another drive shaft 52.
• a bearing 56 mounted on a mounting plate 58 having being held in place by support members 65.
• an exit port 72 At the bottom of chamber 3 is an exit port 72.
• screw auger 80 Connected to drive shaft 52 is a screw auger 80.
• screw auger 80 might have an 10-inch diameter centered over a 16-inch outlet port 72.
• a pair of cylinders 88 Arranged on either side of screw auger 80 are a pair of cylinders 88 having a plurality of lugs 96 mounted in a predetermined manner thereon. i should be noted that the bottom of chamber 3 is curved so as not to create any dead space between the lugs 96 on cylinder 88 and the bottom of chamber 3.
• Motor drive means for rotating cylinders 88 on axles 104 are not shown but their location would be obvious to one skilled in the art.
• the rotations of cylinders 88 may be any one of a combination of three movements with both cylinders 88 being rotated clockwise, both cylinders 88 being rotated counterclockwise or having one cylinder being rotated clockwise and the other cylinder being rotated counterclockwise.
• Cylinder 88 may be rotated at a rotational speed that may be from 1/lOth to 1/2 the speed of screw auger 80.
• feed valve means 120 and discharge valve means 126 are simply conventional style gate valves that will allow the feed to enter chamber 3 and allow the feed material to exit chamber 3.
• a source of nitrogen 135 which provides purging nitrogen to chamber 3 through a line 140 including a valve 148.
• the system of the present invention contemplates batch feeding of a tire liquefaction processing apparatus by having the interlocking solid material, namely the shredded tires, enter through valve means 120 which is then closed.
• discharge valve means 125 being closed prevents any of the shredded tires from entering the processing apparatus.
• valve 148 With both valve means 120 and 125 closed, valve 148 is open to allow nitrogen to enter chamber 3 to purge the oxygen that has entered with the tires. After the oxygen level has dropped to a suitable level, valve 148 is closed, discharge valve 125 is opened, and motors 27 and motors not shown are energized causing the screw auger 80 to rotate driving the shredded tire material out of bin 3. However, as happens in many cases, the shredded tire will bind because of their interlocking nature. Screw auger 80 then has a tendency to tunnel through the bound material. When binding occurs, only the tire material within the range of screw auger 80 would be moved. It is at this junction that the operations of cylinders 88 by their motor drive means keep the tire material in motion so that the tire material is being fed to auger screw 80 and thus preventing the tunneling effect.
• discharge valve means 125 Upon removal of the shredded tire material from bin 3, discharge valve means 125 maybe closed and the system shut down until the next batch is ready to be processed.
